A generic dunny mayfly

By

One day I was given this fly by a friend, but I only got one.

The finished fly - CDC and extended body
The finished fly
 

I found it nice and convincing and decided to put it away until tying time.
During the summer 2006 I fished it in Tuscany - Italy and lost it.

A few weeks ago my job took me to Jutland where I had a meeting close to some danish streams. I spent an afternoon with Ripley Davenport (known by regulars in the GFF forum and Pix section) at the banks of one of them. As it got darker we witnessed one of the most hysteric hatches I have ever seen. Duns crawled up and down our waders. Nymphs were emerging through the surface and duns penetrated the film to get to the buttom.

Photographing in the sparse light was difficult, but we got some pictures, which inspired me to take up this pattern again - before it escaped my memory.

I know the tail and color is not realistic in this specimen, but this is a generic pattern and it will probably show it's effectivness just the same.

Nice fly! As my practice shows there is no use to make such complicated steps. I use only 2 cdc feathers for both extended body and the wing. One disadwantega - it work only for one trout and the is totally destroyed, but for many graylings)
